SPINNING-MACHINE.

Application filed November 4, 1912.

To (ZZZ whom it may concern:

Be it known that l, WALTER H. YOUNG, a citizen of the United States ofAmerica, and resident of Pittsfield, in the county of Berkeshire andState of Massachusetts, have invented certain new and usefulimprovements in Spinning-Machines, of which the following is a full,clear, and exact description.

This invention relates to spinning machines and more particularlypertains to certain improvements in spinning frames by means of whichc'ertainkinds of fancy yarns designed or intended to be woven intonovelty fabrics are produced; that is the yarn produced in the spinningframe under the exercise of this invention is one in which a pluralityof strands, rovings or yarns of different colors are twisted together insuch a manner that for portions of the length of the yarn one of thestrands is helically intertwined with the other, the helical trend orpitch of both of the strands being similar while in relativelyintermediate intervals in the length of the yarn one of the strands iscaused to encircle the other in closely disposed coils or convolutions,thereby giving a spotted or striped aspect to the yarn for theproduct-ion of novelty effects in the fabtie into which the yarn isfinally woven.

To this end the invention consists in the provision,--in a spinningmachine which may be of the most usual character and which comprises aplurality of yarn supplying spools, a plurality of sets of deliveryrolls respectively corresponding to the supply spools, thespindle-carried bobbins on which the yards are wound, and twisting meansbetween the delivery rolls and the bobbins,of means for impartingrelatively intermittent rotary and continuous rotary movement to thedifferent sets of delivery rolls so that in operation the yarns from thedifferent spools at intervals are twisted together 011 comparativelylong; and similar helical lines, and then while one of the yarns has itsprogressive movement toward the bobbin temporarily stopped, the otheryarn being continuously delivered is twisted in closely woundconvolutions about a given portion of the temporarily stationary yarn,

such action being repetitive throughout the.

time in which the spinning machine runs.

The invention is descrlbed 1n conpmction Specification of LettersPatent.

with the accompanying drawings and is set forth in the claims.

In the drawings: Figure 1 is a front elevation of a portion of aspinning machine frame equipped with the present improved mechanism.Fig. 2 is a sectional elevation as taken on line 2*2, Fig. 1. Fig. 3 isa partial sectional elevation, on a larger scale, to more clearly showguiding means for the yarn. Fig. 4.- is an end elevation of sulficientof the machine to show the means for imparting the continuous andintermittent rotary movements to the two sets of delivery rolls. Fig. 5is a sectional view, on a larger scale. as taken on the line 55, Fig. 1,of a detail of construction to be hereinafter re ferred to. Fig. 6represents in side elevation a modified form of the means for impartingthe relatively continuous intermittent movements to the two sets ofdelivery rolls. Fig. 7 illustrates forms of fancy yarns such as may beproduced under the workinn of this invention.

In the drawings, in which a spinning frame of usual construction isshown. A and B represent spools on which yarns of different colors arebeamed.

C represents one set of delivery rolls and D represents another settherebelow, these sets consisting of a pair of parallel separated longshafts or rolls a and a and a and a, sectionally formed idler rolls aresting); in the cradle-like supports therefor formed by the rolls a anda or a and a, the same always accommodating:themselves peripherally tosuch rolls and assuring proper tension on the yarns running through themso that under the rotative movement positively imparted by one roll ofeach set, the yarns will be drawn oil from the beams A and B, thencepassing; in en- ,Q'ae'ement with the yarn guides 7) and b and thence tothe rings (Z on the ring" rail E to be twisted and wound on the bobbinsf 7 carried on the spindles 7 which are individually rapidly driven allas usual.

In the machine here represented, the rolls a and a are continuouslydriven at uniform speedby means as follows: On the driving shaft F, aspur gear wheel G is aflixed. and on the endwise projecting portion ofthe drawing roll a of the lower set D a spur near wheel G is provided;the gear train generally indicated by G between the gears i of the onefrom the other.

G and G forming the means for the driving The drawing roll a being thuspositively and continuously rotatively driven, its companion roll a" isdriven as usual by being geared to it at the opposite end of thespinning frame from that at which the gearing train G, G

G is located. Thus it is apparentthatthe vendwise projecting end asprocket wheel h alongside which is a loose sprocket wheel in. Thedriving shaft F has a sprocket wheel ,m ailixed thereon, and a sprocketchain J runs around a fixed sprocket wheel m and the loose sprocketwheel is whlch is an extension or appurtenance of the drawlng roll a,-such latter sprocket wheel is being merely a guide wheel for thechain.

n represents a chain tenslonlng wheel.

The chain is shown as provided with studs 0 projecting laterallytherefrom for engaging and occasionally imparting rota-tive movements tothe fixed sprocket wheel h, the frequency of this action beingdeterminedby the distancing of the studs along the running length of the chain.For steadiness of the running action of the chain, the same as shown inFig. 5 is provided'with the studs 0" duplicated'at oppositesides of thechain, a second fixed sprocket wheel 72/2 being provided on the roll a"at the side of the chain guiding sprocket "wheel 70' which is oppositefrom the fixed skewed is prevented.

By this duplicated provision of fixed wheels h and kand the opposite laterally extending studs 0, the tendency of the chainand its studs to become In the operation when a chain stud 0 is inengagement with the sprocket wheel h the set of drawing rolls a and awill be rotatively operated for the delivery of yarn from the beam A atthe same rate as that of the delivery of yarn continuously from the'beamB so that at such time under the usual twisting action between thedelivery rolls and bobbins, the yarns will be intertwined oncomparatively long helical lines; but when the'stud passes away fromengagement with the sprocket wheel h, the set C of drawing rolls willremain idle and the advancement of the yarn thence forward to thebobbins will temporarily cease, that is until another chain stud arrivesto engagement with'the sprocket wheel h; and in this time of cessationof the advancing movement of the yarn forward of the delivery rolls Cand forward 'of the produced when twisted while running along 7 togetherat the Same speed. Different examples of these fancy'yarns are indicatedin Fig. 7,-it, of course, being understood that if'spots are to beuniformly distanced inthe length of the yarn the chain studs will becorrespondingly uniformly spaced, while if desired'that there should bea non-uniformity of the spacing of the spots there will be acorresponding variation in thespacing of the chain studs.

The mechanism represented in Figs. 1 and 2 is such as would be 'employedonispinning frames already manufactured andmnow in use, as thegear trainthere-shown-is the usual one; but in caseswhere thespinning frames inwhich my invention is :to be embodied are newly designed, an'arrangementsuch as represented in Fig. 6 may advan tageously be provided, thatis'to say, one of the rolls a of the upper set would have a pair ofsprocket wheels h, 7L2 aflixed'thereon at opposite sides of the chainguiding Wheel is, substantiallythe same as represented in Fig. 5. One oftherolls-"a of the other drawing roll set would have a sprocket wheel t'aflixedthereonfthe shaft F would be a power shaft having asprocketW-heel u aflixed thereon, and the sprocket chain J 2 havingthestuds as before described, here engaging the sprocketwheels, h, -h,-would impart their intermittent rotative movements to the uppersetofdelivery rolls.
